Your Spellbook for Thought

Local-first notes with an on-device assistant — no cloud account required.

Grimoire is a note-taking app with a built-in AI assistant that runs entirely on your machine. No internet required. No data leaves your desk. Just you, your notes, and a little magic.

  • Runs on your machine — notes and assistant stay local.
  • Markdown-native workspace you can use fully offline.
  • Open source under GPL v3; no account or cloud required.
Installers coming soon Help and docs

Pre-built installers for Windows, macOS, and Linux are not available yet — they are on the way. Until then, use GitHub for source and release updates, or see the download page for details.

How Grimoire differs in approach

Factual contrasts — not a scorecard against any single product.

Compared with a typical cloud notebook

  • Your vault stays on disk you control; sync is your choice, not a product requirement.
  • Works without an account; there is no vendor-hosted copy of your notes by default.
  • Offline-capable core — your notes remain usable when the network is not.

Compared with chat in a browser

  • Notes are first-class: structure, links, and search stay in one app, not only in a chat transcript.
  • The assistant can use your vault context locally instead of living only in a browser tab session.
  • No subscription to a hosted model is required; local models (e.g. via Ollama) are optional.

What you get in the app

Capabilities that reinforce the same idea: your notes and assistant stay under your roof.

Completely Local

Your notes live on your machine and nowhere else. No cloud, no sync, no third-party servers. Grimoire works fully offline — even the AI.

Markdown Native

Write in Markdown with a distraction-free editor. Format, link, and organize your thoughts with the syntax you already know.

AI That Knows Your Notes

A built-in assistant powered by Ollama runs entirely on your hardware. Ask questions, summarize, and explore your knowledge — privately.

Open Source, GPL v3

Grimoire is free software. Inspect the code or fork it. Your tools should respect your freedom as much as your privacy.

Why we built it

“A grimoire is a book of spells — but yours holds something more powerful: everything you know.”

We built Grimoire because we believe your second brain should be yours alone. Private by architecture, not by policy.
